3M 7100063701 Scotch-brite Exl Unitized Wheel 1.5 in Ao

Product Description

The 3M 7100063701 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel uses aluminum oxide (AO) abrasive mineral embedded in a soft, conformable, layered construction that maintains consistent abrasive contact throughout the life of the wheel. With a 1.5-inch diameter and a 0.188-inch arbor bore, this wheel mounts directly on rotary tools, die grinders, and bench-top spindles. It weighs 0.01 pounds, making it practical for precision hand-tool and automated finishing operations. Licensed fabricators, machinists, and metal finishing technicians are the primary installers and users.

This wheel is suited for edge finishing, deburring, and light surface conditioning on fabricated metal parts, tubing, sheet metal edges, and formed plastic or composite components. Its conformable construction makes it particularly effective in robotic and automated processing cells where the abrasive must maintain contact with complex contours and irregular part geometries. It is equally effective in manual bench work where consistent, repeatable finish quality is required across production runs.

Key Features

• Soft, conformable unitized construction conforms to complex part geometries including curved and irregular edges
• Aluminum oxide abrasive mineral delivers consistent cut on metal alloys, plastics, and composites
• Layered construction allows wheel edge to be dressed for targeted deburring, finishing, and polishing
• Bidirectional operation — runs clockwise or counterclockwise without performance loss
• Minimizes heat build-up, reducing thermal impact on heat-sensitive base materials
• Resists smearing for cleaner surface results and reduced prep time between operations

Compatibility

Designed for use on rotary finishing tools, die grinders, and spindle-mount equipment accepting a 0.188-inch arbor. Suitable for finishing and deburring operations on metal alloys, plastics, and composite materials.

Installation Notes

Mount this wheel on a compatible rotary tool or bench spindle with the correct 0.188-inch arbor before powering the machine. Confirm the tool RPM rating does not exceed the maximum rated speed of the wheel before operation. Always wear appropriate eye protection and gloves when operating abrasive wheels. Inspect the wheel for damage or irregular wear before each use and dress the wheel edge as needed to maintain effective cutting action.
